R plus s equals 4 2r plus 3s equals 8?
r + s = 4 and 2r + 3s = 8 multiply the first equation by 2 giving 2r + 2s = 8 subtract this from the second equation giving s = 0 So r = 4 and s = 0.
Can you find a pattern to connect the row with it's sum Row- 0 1 2 3 4 5 6 Sum- 1 2 4 8 16 32 64?
The sum = 2r : where r is the row number.
What is 12-2R?
12-2r = 10
How do you solve 2r-1 equals 9?
2r-1=9 2r =10 r =5
What do you times to -2r to get -13?
11
2r plus 2s equals 50 and 2r minus s equals 17?
2r + 2s = 50 2r - s = 17 therefore 4r - 2s = 34 Add so that you can eliminate one of the variables: 2r + 2s = 50 4r - 2s = 34 ---------------- 6r + 0s = 84 Solve for r: 6r = 84 r = 14 Substitute r into one of the original equations: 2(14) + 2s = 50 28 + 2s = 50 2s = 22 s = 11 Doublecheck with the other original equation: 2(14) - 11 = 28 - 11 = 17
R plus s equals 4 2r plus 3s equals 8?
r + s = 4 and 2r + 3s = 8 multiply the first equation by 2 giving 2r + 2s = 8 subtract this from the second equation giving s = 0 So r = 4 and s = 0.
What is the sum of r - 10 and 100 - 3r?
r - 10 + 100 - 3r = -2r + 90
What is the definition of natural population?
The difference between the number of 2s and the number of 4s in a sum.
Can you find a pattern to connect the row with it's sum Row- 0 1 2 3 4 5 6 Sum- 1 2 4 8 16 32 64?
The sum = 2r : where r is the row number.
How do you do absolute 2r plus 9 absolute equals 5?
|2r + 9| = 5 So 2r + 9 = 5 or 2r + 9 = -5 so that 2r = -4 or 2r = -14 r = -2 or r = -7
4R + 3s + 2r = 6r + 3s is what property?
The equation 4R + 3s + 2r = 6r + 3s is an example of the distributive property of addition, where the term 4R is being distributed over the sum of 2r and 6r. To see this more clearly, we can rewrite the equation as: 4R + 3s + 2r = (4R + 6r) + 3s Notice how the terms 4R and 6r are combined and the distributive property allows us to simplify the left-hand side of the equation.
What is 12-2R?
12-2r = 10
What is 4r2-25 factored?
4r2-25 = (2r)2-52 = (2r-5)(2r+5)
How do you solve 2r-1 equals 9?
2r-1=9 2r =10 r =5
What do you times to -2r to get -13?

What is 2r plus 5 less than negative 1?
2r + 5 - - 1 When simplified: 2r + 6
